Abstract: 970,708. Making typewriters; soldering. T.S. PRECISION ENGINEERING Ltd. March 30, 1961 [April 1, 1960], No. 11701/60. Headings B3A and B3R. In soldering a solder-loaded type-piece to a type bar the solder is melted by induction heating. To solder a type piece to a type bar segment of a typewriter the segment is held by levers 4 on a jig 2 with the type bars extending upwardly and the slotted typepiece preloaded with solder is located in a type location block 6 provided with a holding electromagnet. A pedal is depressed half way to energize the electromagnet and a type bar is pivoted downwardly so that its free end lies in the slot of the type-piece. A radio frequency induction heater 8 is energized to melt the solder and then the pedal is fully depressed to operate an air valve supplying cold air through nozzles 11 to the joint. Soldering of type-pieces to the other type bars is similarly effected. A cam device 13 slidable along a bar 14 has a bevelled upper projection and a lower projection, the upper projection by its engagement with a type bar causing it to move foward for easy selection and the return of a type bar from its soldering position causes the bar to engage the lower part of the cam and so move it along the bar 14 to thrust the next bar forward. A type-piece magazine 18 comprises an outer stationary casing 19, an inner cylindrical container 20 and an intermediate cylindrical shutter 21. The container 20 is mounted for rotation within the casing 19 and comprises 48 type-piece compartments 23 arranged in four annular layers of twelve and the casing has four apertures 24, one above the other to register with the openings of the compartments. The shutter 21 has four offset apertures each registering with one of the layers of compartments and each is three compartments long. The container is rotated through 30 degrees each time the coil 8 is energized and the shutter is rotated through 30 degrees at every fourth operation of the coil so that only one compartment 23 is open at a time. A second shutter 26 between the casing and shutter 21 is moved over the apertures 24 when the magazine is operated. Type-pieces may be soldered to the type bars of computers or accounting machines. Specifications 866,830 and 970,709 are referred to.

Abstract: 556,038. Production of organic epoxides. SHELL DEVELOPMENT CO. Sept. 12, 1941, No. 11723. Convention date, Sept. 17, 1940. [Class 2 (iii)] Organic epoxides, e.g. olefine oxides, hydroxy epoxides, halogenated epoxides, or polyepoxides, are produced by the reaction of a halohydrin. e.g. an olefine halohydrin, a glycerine halohydrin, or a glycerine halohydrin monoether, with a base or basic-acting compound, by separately introducing the two reactants into a reaction zone where the mixture is directly contacted with live steam at, e.g. sub- or super-atmospheric pressure so that the organic epoxide is vaporized and separated. from the reaction mixture substantially as soon as it is formed therein, and continuously rectifying the vaporous mixture out of contact with the basic compound to separate unreacted halohydrin from the organic epoxide and steam. The base or basic-acting salt &c.,. e.g. an alkali or alkaline earth metal hydroxide or oxide, or a carbonate, bicarbonate, borate, ammonium compound or organic compound, may be used in substantial excess of that necessary for the reaction. The separated, unreacted halohydrin may be returned continuously to the reaction zone. In an example the rectifying zone forms the upper, and the reaction and by-product withdrawal zones the lower part of a vertical glass tube used for the preparation of epichlorhydrin from a mixture of glycerol dichlorhydrins, using an aqueous lime slurry.

Title: Improvements in and relating to gas turbine plant
Inventor: WELSH ROBERT JAMES
IPC: F02C7/30
Filed: 1948-04-29
Abstract: 645,906. Gas turbine plant. ENGLISH ELECTRIC CO., Ltd. April 29, 1948, No. 11738. Divided out of 642,215. [Class 110(iii)] [Also in Group II] In a combustion product gas turbine plant a substance likely to condense and deposit in a turbine stage is separated out before that stage in a centrifugal or other settling chamber in which the working- fluid is brought to, or below, the dew point of that substance. Preferably, the working fluid enters the chamber at a temperature 10‹C above the dew point and is cooled in the chamber to 10‹C below the dew point. Substances with different dew points may be separated out in two or more chambers arranged in series. The cooling may be effected by a spray of sea-water and admixture with cooler air. Fig. 2 shows a plant in which the turbine 6 works over a temperature range above the dew point of the deleterious substance and exhausts at a temperature only a little above that dew point. The working fluid passes to a separating chamber 5 where it is cooled to below the dew point by admixture with air bled from the compressor 1 by line 7 and by a spray of sea-water introduced at 19. The necessary quantity of cooling air increases with decreasing load and serves also to maintain the mass flow through the turbine 9. In a modification, some cooling in the chamber 5 is effected by air from the compressor delivery which is passed through a coil in the chamber in fluid parallel with the exhaust heat exchanger. The temperatures in the chamber 5 are controlled by a valve 7a, Fig. 2, and, in the modification, additionally by valves in the parallel lines to the cooling coil and the exhaust gas heat-exchanger. A cyclone type separating chamber 15, Fig. 3, has a tangential entry 13 for the hot gases, an entry 17 for the admixture of cooling air, a spray nozzle 19 for sea-water and an exit 18 for the purified gases. The chamber has a removable lining 16 and is closed by a pressure-resisting lid 11.

Title: Improvements in radio-transmitters
IPC: H03C1/50
Filed: 1946-04-17
Abstract: 614,243. Modulating systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and PRICE, T. H. April 17, 1946, No. 11887. [Class 40 (v)] Relates to phase-swing radio transmitters of the kind described in Specification 555,384, in which the carrier is fed to the aerial through two paths in which it is phase-modulated in opposite senses by the signal; and comprises a modified arrangement of the valve circuits in the two paths. The carrier is fed from a source RF to a tuned circuit g which is balanced about earth E and is connected to the control grids of two push-pull pairs of pentode valves V1, V2, V3, V4. The valves V1, V2 have individual tuned anode circuits 1, 2 and the valves V3, V4 a common tuned anode circuit 3. The modulating signal LF is applied in phase opposition to the suppressor grids of the valves V3, V4. The voltages at the anodes of the valves V1, V2 have the steady values indicated by v1, v2 in the vector diagram, whilst the voltage at the joined anodes of the valves V3, V4 are in phase with v1 or v2 and vary in sense and magnitude with the polarity and strength of the modulation LF. The latter voltages are shifted 90 degrees forward to the positions v3 or v4 by the networks comprising the tuned anode circuits 1, 2, 3 and the condensers C1, C2, and are combined vectorially with the voltages at the anodes of V1, V2. The resultant at the anode of V1 takes up varying phase positions va ... vd, and at the anode of V2 the positions va1 ... vd1. These phase-modulated voltages may be separately amplified and are eventually combined at the aerial stage to radiate an amplitude-moduated wave. Inductive reactance may replace the capacities C1, C2. If the bias voltages on the suppresser grids of the valves V3, V4 are unequal, the outputs in the condition of no modulation may be in the phase positions va, va1 instead of the positions v1, v2.
